Strain msl/fasc/tnd post grp at thi lev, left thigh, sequela

This code signifies a chronic or late-effect injury to the muscles, fascia, or tendons located at the back of the left thigh. This typically involves the hamstring muscle group and refers to the long-term consequences or complications of an initial strain, rather than the acute injury itself.

Apply this code when documenting a patient presenting with persistent pain, weakness, or functional limitations in the left posterior thigh that are directly attributable to a previously sustained strain. This is appropriate for follow-up encounters addressing the ongoing management of such an injury after the acute phase has passed.

• Always sequence this code after the code for the initial acute injury, if known and still relevant.
• Ensure documentation clearly indicates the left thigh and the chronic nature or sequela of the strain.
• Do not use for acute or initial encounters of a hamstring strain; those require an acute injury code.
